The SPDF is a project of the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center. SPDF consists of web-based services for survey and high resolution data and trajectories. The Facility supports data from most NASA Heliophysics missions to promote correlative and collaborative research across discipline and mission boundaries. Read More here.
Changed Responsibilities in Archiving NASA Heliophysics Data
As many of you probably already know, NASA’s Heliophysics Science Division at NASA HQs issued a revised Heliophysics Science Data Management Policy in 2009 (see http://hpde.gsfc.nasa.gov/Heliophysics_Data_Policy_2009Apr12.html). This revised policy redefined the Heliophysics role of the National Space Science Data Center (NSSDC) at Goddard to be solely that of a “deep archive” and defined a new role for the Space Physics Data Facility (SPDF) to be one of two “active Final Archives” charged to work with NASA HQs to ensure the long-term accessibility and availability of all important NASA heliophysics data.
This policy has generally superseded all prior definitions of the archiving role of NSSDC in heliophysics mission PDMPs or other arrangements. Delivery of all archival products from Heliophysics missions or investigations should be expected to be to the SPDF rather than NSSDC. If you have any concerns or questions, please contact us by phone or through the "Feedback" link on this page.
New CDF Version 3.4 Software ReleasedCDF now supports two new data types, INTEGER*8 (signed 8-byte integers) and time_TT2000 (which correctly and unambiguously handles leap seconds and carries nanosecond precision in 8 bytes). CDF 3.4 also includes numerous bug fixes, security improvements and performance enhancements. USERS ARE STRONGLY URGED TO UPGRADE TO THIS NEWEST VERSION AT THEIR EARLIEST CONVENIENCE. Please see http://cdf.gsfc.nasa.gov. Updates for Perl, IDL, Matlab and Java interfaces are also available on this site.
SSCWeb and the 4D Orbit View Are Running on a More Powerful ServerThe SSCWeb service and its database have been fully converted to Linux and are now operational on a new server. Users should see greatly improved performance of the SSCWeb user (http://sscweb.gsfc.nasa.gov) and web services (http://sscweb.gsfc.nasa.gov/WebServices/) interfaces, as well as server-side database operations and computations of the 4D Orbit Viewer (http://sscweb.gsfc.nasa.gov/tipsod/).
SPDF's Partnership with the RBSP and MMS MissionsBoth RBSP (http://rbsp.jhuapl.edu/) and MMS/MMS-SMART (http://mms.gsfc.nasa.gov/, http://mms.space.swri.edu/index.html) have decided to use to our CDF format for their public science data and to supply their public data to our CDAWeb service as part of their commitment to ensure their data are properly archived and to make their science data fully public and easily accessible. We are gratified that these major new projects find our services useful and relevant, and we look forward to serving these data as they become available. Note RBSP's scheduled launch is later this summer.
